Short answer: the ELAC Debut 3.0 DB63. It ranks #41 of 131 bookshelf speakers by sound quality at $499; the Chesky LC1 ranks #122 and costs $1000, so there is not much of a tradeoff to weigh.
What the ELAC Debut 3.0 DB63 offers: 1” aluminum dome tweeter with a distinctive partial-lens waveguide design paired with a 6.5” third-generation aramid fiber cone woofer, in a robustly built cabinet for the price. Shallow bass rolloff (F3 76Hz, F10 40Hz) allows placement close to a wall without excessive boominess, useful for smaller living rooms. Solid measured performance for the price: on-axis linearity within about 2.5dB, impedance dipping only to about 4.4 ohms (easily AVR-driven), and roughly 20-26dB of usable dynamic range. A clear improvement over its sibling ELAC DB62, which has a sibilance issue tied to the crossover that can’t be fixed with EQ. Wide horizontal radiation of about ±60°, giving a spacious soundstage. Distortion looks good at a moderate 86dB and still reasonable at 96dB. Takes well to EQ correction - the reviewer provides a specific filter set (a low-shelf boost at 650Hz plus peaking cuts/boosts at 550Hz, 660Hz, and 3kHz) that meaningfully smooths out its known deviations. Watch for: A dip in the lower midrange (300-600Hz, about 1.5dB) reduces vocal warmth and can make voices sound slightly hollow. A high-Q resonance around 650-750Hz shows up clearly in measurements, though the reviewer couldn’t reliably hear it in his own A/B testing. A dip around 2-3kHz (roughly 1-2dB) slightly reduces speech intelligibility and attack in the upper midrange. Directivity droops above about 2kHz as the midwoofer narrows toward its beaming frequency while the tweeter’s pattern behaves differently - an inherent trade-off of physically separated drivers that can’t be fully corrected without introducing other issues. Multitone distortion crosses the reviewer’s 3% threshold in the 200Hz-1kHz range, and adding a subwoofer at an 80Hz crossover only modestly reduces it. Toeing the speaker away from the listener loses noticeable top-end air and cymbal energy, giving a softer upper register. Practical loudness ceiling is around 90dB at typical listening distance before midrange distortion and bass attack begin to degrade. Still needs a subwoofer for extension below about 40Hz.
What the Chesky LC1 offers: Premium build details: silver-soldered crossover with film capacitors, dual inertially-balanced 8” passive radiators, and a multi-layer, non-resonant cabinet construction. Wide horizontal radiation of about ±60-70° through the midrange, in the reviewer’s preferred range. Extremely easy to drive electrically (minimum impedance about 8.4 ohms, minimum EPDR 5.4 ohms). Distortion shows good separation between second- and third-order harmonics at both 86dB and 96dB. The reviewer took the unusual step of verifying his measurements weren’t due to a defective unit - he impedance-swept both speakers, then corresponded directly with the manufacturer, whose own measurements matched his, confirming the sound reflects the actual product design. Watch for: Overall tonal balance sounded dull, hollow, and unengaging in extensive listening, with recessed vocals (both male and female) and minimal bass - the reviewer independently confirmed the same impressions auditioning the speakers at an audio show, ruling out a fluke with his own pair. Essentially no meaningful bass below about 90-100Hz in-room (F3 71Hz, F10 49Hz), well short of the 50Hz frequency-response spec, and measured sensitivity (about 81.4dB) runs well below the 86dB claimed. A pattern of peaks and dips across the spectrum, rather than a simple tilt, makes different instruments sound inconsistent depending on what frequency range they occupy - an unusually difficult profile to characterize or EQ around. Center-image focus never locked in properly regardless of listening position - traced to a measurable mismatch between the two individual speaker samples’ on-axis response, an unusual quality-control issue for a simple dome-tweeter design. A cancellation/lobing region just below the tweeter axis, likely from shallow first-order crossover slopes and some crossover-region overlap, means listening position needs to stay right at or slightly above tweeter level. Elevated multitone distortion in a region tied to a cone-edge/surround resonance (a known issue across several driver brands), only marginally improved by adding a subwoofer. Sample-to-sample driver measurements showed real inconsistency between the two review units’ tweeters and midwoofers. A cosmetic gap around the tweeter’s flush-mount cutout suggests room for tighter fit-and-finish.
Buy the ELAC Debut 3.0 DB63. It ranks higher for sound quality than the Chesky LC1 and costs less, so there is no real case for the other one.
If sound quality matters at all to you, skip the Chesky LC1. It ranks near the bottom of the 131 bookshelf speakers, so look higher up the list instead.
